Be it known that l, lemon DUPIN, a citizen of the United States, residing at Groveton, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

This invention relates to rail joints and has for its object to provide a device of such class, in a manner as hereinafter set forth, for connecting the opposing ends of a pair of track rails together without the employment of nuts and bolts, at the same time providing for the necessary contraction and eX- pansion of the track rails due to climatic influences.

Further objects of the invention are to provide a rail joint which is readily assembled, strong, durable, efficient and inexpensive.

`With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood thatchanges, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views :Figure 1 is a side elevation of a rail joint in accordance with this invention. Fig. 2 is a top plan view. Fig. 3 is a section on line X-Xf Fig. 1. Fig. et is a section on line Y-Y Fig. 1. Fig. 5 is an elevation, broken away, of a rail.

Referring to the drawings in detail 1 and 2 denote a pair of track rails and each includes a head 8, web t, and base 5. Each of the webs 4 is provided with a longitudinally extending rectangular slot 6, one end of the latter being of greater width than the other, as indicated at 7. The slots 6 are arranged in proximity to the free ends of the webs 4.

The reference characters 9 and-10 denote a` pair of fish plates and each has a base fiange 11. The fish plates 9, 10, are positioned against the opposed sides of the webs 4 of the track rails 1, 2, when the ends of said rails oppose each other and each of said Specification of Letters Patent.

Patented Jan. 11, 1916.

Serial No. 13,837.

fish plates is provided with a longitudinally extending rectangular opening 12 and a longitudinally extending rectangular opening 13, the latter being of greater width than the former. rlhe opening 12 is disposed centrally. with respect to the opening 13 and said openings 12, 13, conform in contour to the openings 6, and the openings 12, 13 of the fish plates 9, 10, when the fish plates are mounted in position, are arranged in alinement with the openings G, formed in the webs 1l of the track rails 1, 2.

The outer face of each of the fish plates 9, 10, is provided with beveled surfaces 1i above and below the openings 12 and the outer face of each of the fish plates 9, 10, is cut away, to provide seats 15 above and below the openings 13.

The fish plates and track rails are coupled together by coupling members 16, having end flanges 17, and each of these latter has its inner face beveled. The end flanges eX- tend transversely with respect to the member and said beveled faces of the said end flanges when the coupling members are positioned in the openings 12 associate with the beveled surfaces 1f-1 to set up a wedging action whereby the fish plates are maintained in close relation with respect to the webs 4l.

The coupling members are maintained in position by holding members and with each coupling member associates a pair of holding members, the holding members of each of the pairs being indicated at 18 and each pair of holding members is extended through alining openings 13. Each holding member has each end provided with a flange 19 and which when the holding member is in position abuts against a seat 15. The holding members are maintained within the alining openings 13 by a fastener member which is in the form of -a web and is indicated by the reference character 20. The fastener member is driven between a pair of holding members 18 and one end of the fastener member 2O is split and bent upon itself in opposite directions as at 21 to prevent said fastener member from slipping out.

When the members 16 are mounted in position they are extended through the larger ends of the slots or openings 6 and then forced into the smaller ends of said slots or openings. Vhen the fastener members are in position they are mounted in the larger ends of the openings or slots 6.

What I claim is l. A rail joint comprising the combination with a pair 'of track rails each having its web formed with a pair of openings, one of the Openings of each pair being larger than the other opening of the pair, the openings of each pair merging into each other, of a pair of fish plates positioned against Said webs and having openings corresponding in contour to the openings in the web, the openings in the fish plates alining with the openings of' the webs, coupling members extending through the aligning smaller openings and provided with means engaging said fish plates to set up a wedging action, a pair of' holding members extending through the alining larger openings, and a fastener member extending between each pair of holding members for maintaining them in position.

2. A rail joint comprising the combina tion with a pair of' track rails each having its web formed with a pair of openings, one of the openings of each pair being larger than the other opening of the pair, the openings of each pair merging into each other, of a pair of fish plates positioned against said webs and having openings corresponding in contour to the openings in the web, the openings in the fish plates alining with the openings of the webs, coupling members extending through the alining smaller openings and provided with means engaging said fish plates to set up a wedging action, a pair of holding members extending through the alining larger openings, and a fastener inember extending between each pair of holding members for maintaining them in position,'

said fish plates provided with seats, and said holding members having flanges engaging said seats.

3. A rail joint comprising the combination with a pair of' track rails each having its web formed with a pair of' openings, one

of the openings of' each pair being larger than the other opening of the pair, the openings of' each pair merging into each other, of a pair of fish plates positioned against said webs and having openings correspond ing in contour to the openings in the web, the openings in the fish plates alining with the openings of the webs, coupling members extending through the alining smaller openings and provided with means engaging said fish plates to set up a wedging action, a pair of holding members extending through the alining larger' openings, and a fastenerl member extending between each pair of holding members for maintaining them in position, said fish plates provided with seats, and said holding members having flanges engaging said seats, said fastener members being wedge-shape in contour.

4. A rail joint comprising-the combination with a pair of track rails each having its web formed with a pair of' openings, one of the openings of each pair being larger than the other opening of the pair, the openings of' each pair merging into each other, of a pair of fish plates positioned against said webs and having openings corresponding in contour to the openings in the web, the openings in the fish plates alining with the openings of the webs, coupling members extending through the alining smaller openings and provided with means engaging said fish plates to set up a wedging action, a pair ofl holding members extending through the alining larger openings, and a fastener member extending between each pair of holding members for maintaining them in position, said fish plates having beveled surfaces associated with said means of the coupling members to assist in the wedging action.

In testimony whereofl I afiix my signature in presence of two witnesses.
